I am writing a RelativePathService, I want to return all the Java source
paths that is available for the project as roots for searching the file
that will be assigned o the property having the RelativePathService.
Can anyone tell me how to do this ?
Also in the same scenario,
What is the best way to convert "/" to "." during serialization do we need
to do CustomXmlValueBinding ?

Thanks Konstantin. No not java Types, Actually I am trying to browse for
Resource Bundles (*.properties) that is available in the classpath.
Also when I saw your reply for getting IProject , am now forced to ask me a
long standing query, how to do I access the model element inside the Service
classes or any other place ?

IProject proj = element.adapt( IProject.class );
IJavaProject jproj = JavaCore.create( proj );
for( IClasspathEntry entry : jproj.getRawClasspath() )
{
...
}

If you want the text box to show dots, but have slashes written to file,
then you need to write a custom binding. If you'd rather see dots in the
text box as well, but the problem is that the browse dialog is returning
slashes, see RelativePathService.convertToRelative/convertToAbsolute API.
I am assuming that you aren't trying to do this to browse for Java types, as
the framework has built-in support for that that is better than trying to
use RelativePathService.

I found the way the Service class provides the adapt() method which can be
used to make it to adapt to IProject :)
So let me rephrase my question what is the general way to get model element
if I I have,
1. ModelElementType
2.ModelProperty

"IProject proj = element.adapt( IProject.class );
IJavaProject jproj = JavaCore.create( proj );
for( IClasspathEntry entry : jproj.getRawClasspath() )
{
...
}"
Based on the above logic I wrote the the logic to make the roots as follows,
ProjectRelativePathService
.....
roots.add( new Path(iClasspathEntry.getPath() ).toPortableString() ));
.....
and my model property definition
// *** ResourceBundle ***
@Type( base = Path.class )
@MustExist
@ValidFileSystemResourceType( FileSystemResourceType.FILE )
@Service( impl = ProjectRelativePathService.class )
@FileExtensions( expr = "properties" )
ValueProperty PROP_RESOURCE_BUNDLE = new ValueProperty( TYPE,
"ResourceBundle" );
Value<Path> getResourceBundle();
void setResourceBundle( String value );
void setResourceBundle( Path value );
When I run my editor, and click on the browse I see just text for the
classpath entries and no file or folders displayed, but it has files and
folders + filters for .properties file. Not sure what mistake am making.
I also tried doing the following way but same result,
for ( IClasspathEntry iClasspathEntry : cpEntries ) {
if ( IClasspathEntry.CPE_SOURCE ==
iClasspathEntry.getEntryKind() ) {
IPath projectPath =
ResourcesPlugin.getWorkspace().getRoot().getLocation();
System.out.println( "Portable String" +
projectPath.append(
iClasspathEntry.getPath() ).toPortableString() );
File file = new File( projectPath.append(
iClasspathEntry.getPath() ).toPortableString() );
roots.add( new Path( file.getAbsolutePath() ) );
}
}
Can you please clarify what mistake am making ??

<DIV>I am not sure what is the reason - My project was WebProject, as you
said the ClasspathEntry was not returning the absolute path, hence I resorted
your suggestion of using Workspace API and did as follows,</DIV>

<DIV>Unless your project setup is very unusual, this will not produce absolute
paths that are required for roots. More like "/proj/src". You will need to
convert this path to an IFolder using IWorkspace API then call getLocation() on
IFolder to produce an absolute path that's required.</DIV>
